Digital I/O Module BMT-DIO4/21108831326

1. DescriptionThe BACnet MS/TP module with 4 digital inputs and 2 relay outputs with manual control was developed for decentralized switching tasks. It is suitable for accommodating, for example, light switches and window contacts in a room, switching two light strips or controlling louvers. It can also be used to control 2 mo-torized fire dampers. With strong inductive loads, we recommend protecting the relay contacts with an RC element. The inputs can be used as contact or voltage inputs. The inputs and outputs can be switched and scanned by means of standard objects via a BAC-net client. The module address and the baud rate are set by means of two address switches on the front.Suitable for decentralized mounting in serial sub-distributor.

Use the jumper plug to connect bus and supply voltage when the modules are mounted in series.The maximum quantity of modules connected in line is limited to 15 or to a maximum power consumption of 2 Amps (AC or DC) per connection to the power supply. For any similar block of additional modules a separate connection to the power supply is mandatory.
